Hello again. Now it's the right time to explain the whole project that I'm working on to you,because now I have the missing piece,thanks to Thomas and I can exclude one of the reasons why it does not work. What I would like to do is to use a preseed file to preconfigure some options,so that the debian installer does not ask me the relative questions. I've found this tutorial and I've followed,integrating the Thomas suggestions :
https://github.com/Nidouille/Debian-Automated-Installation these are the commands that I have issued : apt update && apt -y install xorriso genisoimage wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-11.5.0-amd64-netinst.iso xorriso -osirrox on -indev /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-11.5.0-amd64-netinst.iso -extract / /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/ chmod +w -R /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/d-i/ gunzip /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/d-i/initrd.gz echo /home/ziomario/Scrivania/PassT-Cubic/ISO/preseed/preseed.cfg | cpio -H newc -o -A -F /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/d-i/initrd gzip /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/d-i/initrd chmod -w -R /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/d-i/ cd /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/ chmod a+w /home/ziomario/Scrivania/PassT-Cubic/ISO/debian-live-11.5.0-amd64-xfce/isolinux/isolinux.bin cd /home/ziomario/Scrivania/PassT-Cubic/ISO/ ./script1.sh orig_iso=debian-live-11.5.0-amd64-xfce.iso new_files=debian-live-11.5.0-amd64-xfce new_iso=debian-live-11.5.0-amd64-mod-xfce.iso mbr_template=isohdpfx.bin # Extract MBR template file to disk dd if="$orig_iso" bs=1 count=432 of="$mbr_template" xorriso -as mkisofs \ -r -J --joliet-long \ -V 'd-live 11.5.0 xf amd64' \ -o "$new_iso" \ -isohybrid-mbr "$mbr_template" \ -partition_offset 16 \ -c isolinux/boot.cat \ -b isolinux/isolinux.bin \ -no-emul-boot -boot-load-size 4 -boot-info-table \ -eltorito-alt-boot \ -e boot/grub/efi.img \ -no-emul-boot -isohybrid-gpt-basdat -isohybrid-apm-hfsplus \ "$new_files" cd debian-live-11.5.0-amd64-xfce/ LOG : 432+0 record in 432+0 record out 432 bytes copied, 0.000426907 s, 1.0 MB/s xorriso 1.5.4 : RockRidge filesystem manipulator, libburnia project.

ISO image produced: 1320624 sectors Written to medium : 1320624 sectors at LBA 0 Writing to 'stdio:debian-live-11.5.0-amd64-mod-xfce.iso' completed successfully. Yes,the resulting ISO image is bootable,but the preseed file does not stick. The installer stills asks me the questions that it shouldn't , according with the preeseed.cfg file that I've used : d-i debian-installer/add-kernel-opts string intel_iommu=on d-i mirror/http/hostname string http.us.debian.org d-i mirror/http/directory string /debian d-i passwd/root-password password marietto d-i passwd/user-fullname string marietto User d-i passwd/username string marietto d-i passwd/user-password password a d-i passwd/user-password-again password a d-i user-setup/allow-password-weak boolean true so,do you know why it is totally ignored by Debian,according to the commands that I have issued ? Thank you very much.
